DUAL EMISSION LED CHIP

The present invention is a dual emission LED chip that emits light to the upper and lower sides of a PN junction, wherein the duel emission LED chip uses the electroluminescent effect of the PN junction including a P layer and an N layer provided below the P layer, and characterized in that the dual emission LED chip emits light in the upward direction of the P layer and the downward direction of the N layer. The present invention can be applied as a single chip to a field requiring dual emission, thereby enabling miniaturization of applied equipment, and increases power efficiency, thereby reducing manufacturing costs. In addition, as the dual emission LED chip manufactured according to the present invention can be manufactured through a batch process, a separate packaging process is not required. Furthermore, the dual emission LED chip according to the present invention has the effect of increasing light efficiency by reducing the internal total reflection of light generated from an LED. 本发明提供一种双面发光LED芯片，其为
